anime recommandations for a newbie

Helloo I'm relatively new to anime. I've watched some of the famous ones like HxH (my favorite so far), MHA, Saiki K, AoT and Cowboy Bebop, currently finishing Naruto Shippuden, JJK and Demon Slayer. I have an idea in mind of some shows I wanna watch next (Samurai Shamploo, Bleach and Fullmetal Alchemist: Brotherhood). But I'd love some less mainstream shows (not that there is anything wrong with them) to broaden my horizon. I’d love some recommendations if possible!
